February 1996 CLK CSN R 1/20 PIN DESCRIPTION N 1 2 o 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 25 26 28 2/20 Type Description Analog Output This pin outputs the luma to allow the user to notch filter it. This pin may be connected to the YIN input for minimum cost applications. VIDEO IN Analog Input This is the CVBS input. An external capacitor is needed for clamp operation. The STV5730A extracts the sync from this signal when the C7 control bit is set. RES Analog Pin it must be tied to an external resistor to control the PLL f0 frequency. FTR Analog Pin it must be tied to the line PLL loop filter. Supply Pin 5V analog supply pin. AVDD DVDD Supply Pin 5V digital supply...
